I'd like to force Safari to mark one of my domains as tracker with new ITP 2.0. I followed the guide here https://webkit.org/blog/8387/itp-debug-mode-in-safari-technology-preview-62/
Since the new Technology Preview version (66) doesn't have ITP Debug mode I've used normal Safari 12.0 on macOS Mojave. After enabling ITP Debug mode and restaring Safari I don't see anything in logs as the guide suggest nor does setting
defaults write com.apple.SafariTechnologyPreview ResourceLoadStatisticsManualPrevalentResource example.com
have any effect (even with Safari instead of SafariTechnologyPreview). Do I need to change any other Safari or OS settings?
